This style of wind power looks cool. The WindTree turns small breezes into electricity. Its production varies with the wind speed and its average output ranges between 1,500 kWh and 2,000 kWh. Peak power is 3,500 kWh.

But I don’t see how it can be effective given the large cost. The WindTree is being offered for installation late in 2017 in the USA and Canada at $67,500 – excluding delivery, installation and taxes (they estimate almost $100,000 total). It really seems to me the prices would have to come down by more than 75% to make any real impact in the market.
